Abstract
Description
Technical Field
[0001] The utility model relates to an airway converter for an electronic anorectal ligator, belonging to the field of electronic anorectal scopes. Background Art
[0002] Anorectal endoscopic ligator is a medical device usually used to assist anorectal surgery. This device is usually used together with an anorectal scope. With the guidance of the anorectal scope, the doctor can accurately find the area that needs ligation, and then use the ligator to perform the ligation operation; the main function of the anorectal endoscopic ligator is to help the doctor perform ligation during the operation to achieve the purpose of hemostasis or blocking blood flow; this device is usually used in operations for anorectal diseases such as internal hemorrhoids, external hemorrhoids, and mixed hemorrhoids.
[0003] The anorectal ligation device needs to perform ligation during the operation, which may cause certain irritation and pain to the patient's anus. The negative pressure aspirator can use the negative pressure suction effect to draw out secretions, blood and other impurities in the surgical area, reduce irritation to the surgical area, and thus reduce the patient's pain.
[0004] When the anorectal ligator is used in conjunction with the electronic anorectal scope handle, when the interface of the anorectal ligator is connected to the negative pressure tube of the electronic anorectal scope handle, it cannot be directly viewed and is prone to misalignment, which can easily cause gas leakage.
[0005] Therefore, the present invention provides a new airway converter for an electronic anorectal ligator which is easy to observe, quick to align and has a good sealing effect. Utility Model Content
[0006] In view of this, the purpose of the utility model is to provide an airway converter for an electronic anorectal ligator which is easy to observe, quickly aligned and has a good sealing effect.
[0007] The utility model is achieved in this way:
[0008] An airway converter for an electronic anorectal ligator comprises a female head arranged at an air outlet end of a negative pressure tube, and a male head arranged at a negative pressure interface of the electronic anorectal ligator, a sealing ring is placed between the female head and the male head, and the female head and the male head are anastomosed and fixed;
[0009] An opening is formed at the upper end of the end where the female connector contacts the male connector.
[0010] As a further improvement, the opening extends to the end surface of the female head, so that the outer contour of the opening is U-shaped.
[0011] As a further improvement, a limiting step is provided on the inner wall of the female head away from the end.
[0012] As a further improvement, the tail end where the female connector is connected to the air outlet end of the negative pressure tube is continuously provided with two bent portions.
[0013] As a further improvement, the angle between two adjacent bending portions is 90°.
[0014] As a further improvement, the angle between the bent portion and the head end of the female connector is 90°.
[0015] As a further improvement, the sealing ring is an O-ring.
[0016] As a further improvement, the opening and the end surface of the female head are rounded chamfers.
[0017] The beneficial effects of the utility model are:
[0018] ① The utility model is equipped with a sealing ring on the male head, and the female head arranged at the air outlet end of the negative pressure tube and the male head arranged at the negative pressure interface of the electronic anorectal endoscope ligator fit each other, and the sealing blockade of the O-ring allows the negative pressure gas in the negative pressure tube in the handle of the electronic anorectal endoscope to be smoothly transmitted to the negative pressure interface of the electronic anorectal endoscope ligator, and then transmitted to the front end of the ligation tube of the electronic anorectal endoscope ligator.
[0019] ② The outer contour of the opening of the utility model is U-shaped. After the opening contacts the male head, the contact surface is smooth and complete, so that there is no obstruction after the male head and the female head contact, and the alignment is accurate. Compared with the traditional pipe docking method, the contact end is only 1-2cm. This method allows the male head to fully penetrate into the female head, and the penetration depth can be increased to 3-5cm, thereby increasing the contact area, and it is not easy to separate due to gas erosion, so as to achieve the anastomosis and fixation of the female head and the male head.

[0029] An opening 101 is formed at the upper end of the contacting end of the female connector 10 and the male connector 20 .
[0030] Further, the sealing ring 30 is an O-ring, which is a widely used mechanical seal, a circular ring mainly made of elastic material, designed to be compressed between two surfaces to form a seal to prevent gas or liquid from escaping. They can be used in static and dynamic sealing applications.
[0031] Furthermore, an annular groove is provided on the outer side surface of the head end where the male head 20 and the female head 10 contact each other, surrounding the female head 10, so that the sealing ring 30 can be put on the male head 20 and then installed into the female head 10 to determine the position of the sealing ring 30, and will not move when the male head 20 and the female head 10 are matched.
[0032] The utility model is equipped with a sealing ring 30 on the male head 20, and the female head 10 arranged at the air outlet end of the negative pressure tube and the male head 20 arranged at the negative pressure interface of the electronic anorectal ligator 50 match each other, and the sealing blockade of the O-ring allows the negative pressure gas in the negative pressure tube in the electronic anorectal handle 40 to be smoothly transmitted to the negative pressure interface of the electronic anorectal ligator 50, and then transmitted to the front end of the ligation tube of the electronic anorectal ligator 50. The specific structure of the electronic anorectal ligator 50 can refer to the patent application titled "An anorectal ligator used under endoscopy."
[0033] As a possible specific implementation of the utility model, the opening 101 extends to the end face of the female head 10, so that the outer contour of the opening 101 is U-shaped. After the opening 101 contacts the male head 20, the contact surface is smooth and complete, so that there is no obstruction after the male head 20 and the female head 10 contact, and the alignment is accurate. Compared with the traditional pipe docking method, the contact end is only 1-2cm. This method allows the male head 20 to fully penetrate into the female head 10, and the penetration depth can be increased to 3-5cm, thereby increasing the contact area, and is not easily separated due to gas erosion, thereby achieving the matching and fixation of the female head 10 and the male head 20.
[0034] As a possible specific implementation of the utility model, a limiting step 102 is provided on the inner wall of the female head 10 away from the end, which is used to limit the penetration depth of the male head 20 to prevent the male head 20 from blocking the turning point of the female head 10, preventing the internal channel from being connected and the negative pressure gas from being smoothly transported.
[0035] As a possible specific implementation of the utility model, the tail end where the female connector 10 is connected to the air outlet end of the negative pressure tube is continuously provided with two bending parts 103, which is suitable for the electronic anorectal scope handle 40 and is easy to install.

[0037] Furthermore, the angle between the bending portion 103 and the front end of the female head 10 is 90°, which is suitable for the internal structure of the electronic anorectal scope handle 40. In addition, through two consecutive bendings, after the female head 10 and the male head 20 are fitted and fixed, they are accommodated in the electronic anorectal scope handle 40. In the event of misalignment and collision, they are not easily displaced and will not be exposed outside the electronic anorectal scope handle 40.
[0038] As a possible specific implementation of the utility model, the opening 101 and the end surface of the female head 10 are rounded chamfers. When the female head 10 and the male head 20 are aligned, there will be no collision of edges and corners, and it is convenient to carefully observe the docking status of the female head 10 and the male head 20.
